Study Notes
Axis of Symmetry
- The axis of symmetry is a line that divides a shape into two mirror-image halves.
- For parabolas (quadratic functions), the axis of symmetry is always a vertical line.
Key Fact
- The axis of symmetry for a parabola represented by the quadratic equation ( y = ax^2 + bx + c ) is given by the formula:
- x = -b/(2a)
Answer Option
- The correct choice is x =.
- This signifies that the axis of symmetry is a vertical line along the x-coordinate.
Axis of Symmetry
- The axis of symmetry serves as a reference line that splits a geometric shape into two congruent halves.
- In the context of parabolas, which are defined by quadratic equations, this axis is always vertical.
Key Fact
- For a given parabola expressed in the standard quadratic form ( y = ax^2 + bx + c ), the axis of symmetry can be calculated using the equation:
- x = -b/(2a)
- This formula identifies the x-coordinate at which the parabola is perfectly symmetrical, enabling clear identification of its vertex.
Answer Option
- The answer indicates that the axis of symmetry takes the form x =.
- This representation confirms that the axis is aligned along the vertical orientation through a specific x-coordinate.
